Philips Applied Technologies assists the product divisions within Philips in development of new, and optimization of existing industrial processes and products. A number of competences at Philips Applied Technologies heavily rely upon high‑end, multi‑physics computational software. In problems related to thermo‑fluid behavior, (micro) fluidics, phase transitions, and multiphysics in general, CD‑adapco software is used. In this article, as an example of application of CD‑adapco solutions within Philips, modeling of ultra‑high pressure lamps (UHP) is considered.
